SPECIFICATION forming part of Letters Patent No. 477,271, dated June 21,1892.

Application filed June 10, 1891. Serial No. 395,769. (No model.)Patented in England November 13, 1889, No. 18,101-

To all whom it may concern.-

Be it known that I, GEORGE ROSE, a subject of the Queen of GreatBritain, and a resident of the city of Glasgow, Lanarkshire, Scotland,have invented certain new and useful Improvements in Apparatus forBurning Hydrocarbon or other Oils for Lighting and Heating Purposes,(patented in England November 13, 1889, No. 18,101,) of which thefollowing is a specification.

My invention relates generally to apparatus for burning hydrocarbon orother oils in the form of spray for lighting and heating purposes; andthe improvements are mainly applicable to that class of apparatuswherein steam generated from water supplied to a coilpipe or chamberheated by the flame is used to spray the oil or oil-vapor in the burneror' consists in certain improvements applicable to such apparatus; andin order that my said invention maybe properly understood I havehereunto appended two explanatory sheets of drawings, whereon- Figure 1shows partly in side elevation and partly in section a spray-lamp. Fig.2 shows in side elevation a different arrangement of spray-lamp. Fig. 3is a vertical section of a spray-lamp; Fig. 4, a side view, partlyinsection, of a spray-lamp; Fig. 5, a vertical section of a spray-lamp.Fig. 5 is a plan view of the basement-tanks, Fig. 5. Fig. 6 is a detailView, partly in section, to an enlarged scale. Fig. 7 is a side view,partly in section, of a spray-lamp. Fig. 8 is a vertical section of anoil-well burner. Fig. 9 represents in sec-' tion an annularsteam-generator as being used instead of a coil-pipe.

On the drawings the same reference-letters,

wellburuer D. (bhown enlarged at Fig. 8.) It is of a similarconstruction to the burners of my prior patents, except that the top ofthe burner is in this case shown as made with a broad flange D, to whichis secured the combu'stion-box or'casing E.

F is the coil-pipe for generating steam, and it is supplied with waterfrom the tank A by means of a pipe connection F.

Oil is supplied fromthe tank B to the oil-well of the burner D by meansof the pipe G,which is provided with acontrolling-valve G. Theself-generated steam from the coil F is conducted down to thesteam-chamber F of the burner by the pipe F The pipe F has or may have aregulating-valve F on it.

In the present invention there is connected to the pipe F a pipe H,leading to the top or other part of the water-tank A. This pipeis forthe purpose of conducting some of the self-generated steam to the tankA, so as to create a pressure therein, and thus obviate the necessity offorcing in air under pressure by means of a hand-pump, as formerly. The

burner-nipple D has an opening or orifice of such size in it that therewill always be sufficient steam generated in the coil F by means of theheat of thelamp-fiame as will supply sufficient steam to give a steadyandregular pressure in the water-tank A and also to spray the oil.

In connection with the water-pipe F is or may be fitted an automaticsupply-regulating valve l. The valve consists of a casing 1, (shown moreparticularly at Fig. 6,) in which works a piston or plunger 1 The casingis narrowed-at one end, so as to form a seat for the piston, and isscrewed or otherwise fitted into the sideof the water-tank A. Connectedto the piston I is a piston-rod I, which passes out through astuffing-box I and through a slot I (shown dotted) or its equivalent inthe handle I of the stop-cock 1 which latter may be of the usualconstruction. The piston-rod I may have stops 1 on it, so that when thepiston is traversed back and forward the handle of the cock I will bereciprocated and the supply of water out off or turned on. The casing 1is open at its inner end 1 To keep the piston I normally closed againstits seat, a spiral spring I or equivalent is provided.

This spring bears on the casing cover 1 which may be perforated, and theback of the piston I WVith this arrangement when the lamp has beenstarted, which may be done by means of naphtha or other volatile oilbeing poured into the box or casing E and ignited, so as to generatesufficient heat to convert the water in the coil into steam,the steampasses from the coil down to the junction of the pipes F and H, where itdivides into two streams, one passing to the burner-nipple to spray theoil and the other passing up the pipe H to the tank A and creatingpressure therein. On the steam-pressure in the water-tank becoming greatthe piston l of the valve I is forced outward against the action of thespring I and the piston-rod traverses the handle I of the cock I and socuts oit the water-supply to the coil. On the pressure falling thespring I forces back the piston to its original position forwater-supply. The valve is or may be so arranged that, as shown, thecock I will be open when the piston I is closed against its seat and thecock will be shut on the piston being forced outward, although it may bearranged to operate in an opposite manner.

The tanks A B may be mounted on top of a trestle or may sit on abracket.

The lamp shown at Fig. 2 has a cylindrical oil-tank 13, supported onthree legs or supports J. The water tank A is in this case TheWater-tank is, as shown, preferably of smaller diameter than theoil-tank B, as a much smaller supply of water is required for the lampthan oil. filling-tube J, to which water from the main or other sourceis supplied to fill this tank A. The burner D is of the sameconstruction as in Fig. 1. The automatic supply-regulating valve I isnot shown as applied to this lamp. With this arrangement thesteam-pressure from the generating-coil is at first allowed to pass intothe top of the water-tank through the pressure-pipe H, so that thepressure in p the tank will balance the pressure in the generating-coil.If pressure were not admitted to the water-tank A through the pipe I-I,there would be a back-pressure along the watersnpply pipe F, which is,together with the ter up to the same level as in the water-tank when thevalve 1 is open, and as a consequence water would flow irregularly, andthus cause the lamp to go out. By having the pressure in the tank and inthe generatingcoil balanced, as aforesaid, water will flow in smallquantities, as required, into the gencrating-coil. When starting thelamp, a small quantity of water is supplied by gravitation to thegenerating-coil by opening the valve 1 on the water-supply pipe. Thevalve I may, if desired, be dispensed with.

In Fig. 3 a lamp is shown having a large oil-tank B, fitted with apocket A on the inside for holding the necessary supply of water. Thepocket A, as will be seen, is fitted icoil of the burner. sists of acoil N, fitted on top of or it may be burner.

supplied with water direct from the tank A by means of the pipeconnection N, and steam to that side of the tank B which is nearer tothe lamp-burner, in order that the heat radiated off the flame may heatup the imprisoned air in said pocket and cause it to expand, and socreate pressure therein. The pressuresteam from the generating-coil F isled into pocket A by the pipe H, which in this case has a valve J on itto regulate the supply of steam to said pocket. The water-supply pipe Fis shown as having asiphon-bend F on it, which is for the purpose ofkeeping a supply of water in the generating-coil F. The bottom of thecasing E is shown in this case as ei g used as the oil-well of theburner D. With this arrangement when starting, the Water is suppliedfrom the pipe F by opening the valve 1 and as it comes into contact withthe heated surface of the generating-coil F steam is at once generatedand by opening the valve J on the steam-pressure pipe II is passed intothe water-pocket A to create or increase the pressure therein. Thisbeing done, the steam-supply to the water-pocket may be turned off andthe steam-supply to the burner turned on by means of a valve on theconnection F (not shown 011 the drawings,) so as to maintain the flameby spraying the oil or oil-vapor in the casing E. The

I pressure in the water tank or pocket A can be thus maintained byturningon a supply of ,steam at intervals from generating-coil F. fittedto the under side of the oil-tank B.

The pocket may be inclosed in a casing form- :ing an air-jacket, so asto retain the heat. The oil is supplied by gravitation, as in the caseof the arrangements at Figs. 1 and 2.

The water-tank A has a The lamp shown at Fig. t works in thesame manneras the lamp Fig. 3, the only diiterence in the construction of this lampbeing that the water-tank A is supported or held v 1 out from theoil-tank B by means of straps c.

The lamp is shown as fitted on a trestle L, which is broken away. Inthis lamp the l valve F is shown for turnin on steam to the 0 burner D.

In Fig. 5 the lamp is shown with a crescentshaped oil-tank B, and intothe hollow of the crescent is fitted the watertank A. The

shape of the tank is shown more particularly in the plan View at Fig. 5l B are strapped together at 0. lower part of the coil, always filledwith wa- The tanks A and In Fig.7 an arrangement is shown whereby steamfor creating pressure in the water is obtained apart altogetherfrom thegenerating- The arrangem ent conaround or inside the generating-coil Fof the Thisauxiliary or pressure coil N is generated in the coil Npasses into the upper A safety-valve N is shown ings it is to beunderstood that I prefer al ways to fit a safety-valve on the water-tankin cases where steam is used to create a pressure therein.Pressure-gages are also used.

With the arrangement of steam-pressure tanks hereinbefore described notonly is the necessity for repeated pumping obviated, but the water inthe water-tank is warmed sufficiently to facilitate a rapid steamgeneration in the generating coil or chamber.

A whistle may be fitted on top of the pressure-tanks to indicate whenthe pressure has reached a certain point, so that the attendant can thencut off further supply of steam.
